DT Swiss has engineered the ultimate aerodynamic combination of wheel and tire interface in collaboration with Continental with a joint tire: the Aero 111. Wheel and tire combinations pre-chosen and designed to be as aerodynamically efficient as possible. Tire Features:. Aero wheels have Aero 111 26mm front tire and GP 5000 STR 28mm rear tire (Front & rear sold separately). Aero 111 tires features 48 `vortex generators` which greatly reduce drag across the entire wheel system freeing up additional wattage. Continental`s Black Chili compound and Vectran Puncture resistant technology. Wheel Features:. Second generation ARC wheels are now built wider and feature even greater aerodynamics with a 62mm tall profile. Available in several distinct profile heights the Dicut 80 is the tallest and most aerodynamic profile built for flat out speed. New redesigned rim shape offers lower drag and smoother airflow between tire and rim interface. The ARC1400 feature a new 240 Dicut Aero hub as well as DT`s classic Aero Comp spokes
